sEE'ROVEMENT IN SEED-:DRILL .AND CORN-COVERER rnc Schedule 'referred toin these Letters Patent and making part pf the same.

To whom tt may concern:

Be it known that WILLIAM A. DONNELL, of Greensbig, Decatur county,Indiana, have invented a new and useful Seed-Drill and Corn-Coverer; andI hereby declare the 1following to be a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,making part of this speciiication.

This invention relates to a machine which is applicable to sowing smallgrain, and also to covering corn after the same has been dropped.

Figure 1 is a perspective view of the machine in condition of awheat-drill.

Figure 2 is a plan, showing the concave-faced pressure-roller attached.

Figure 3 is a transverse section on the line -x, fig. l.

A A constitute an angular frame, to whose forward end the draughtfclevisis attached, and whose rear ends are secured to the outer standards B B.

C is a cross-bar, to whose mid-length the central (and forward)'standard D .is attached.

The brace-bar E of this standard has, at its forward end, an eye, e,through which the @levis-bolt passes.

Attached to the trame A A', and also to the handles F, is a seed-hopper,G, and from the bottom of the said hopper descend seed-conductors H I,the two former of which pass downward through the standards B B', anddeposit the seed at the rear side of said standards, in near proximityto the ground.

The aperture l), through the standard, is so situated as to render anyclogging of the saine bythe earth impossible; and yet to deliver theseed yery accurately7 in the furrow made for its reception.

The conductor, l, does not pass through the standard D, but delivers theseed at the same relative point in the rear of the same as theconductors H H, namely, in the immediate rear of the lower portion cithe standard.

Proceeding from the sides of the frame A A are two metallic bars, J J',which, tending downward and backward, are attached to the standards B B,forming braces therefor', and are further extended backward to formjournal-bearings for the axle of the ground-wheel K, or concave-facedroller L, as the machine may be respectively used as a wheatdrill orcorn-coverer.

When the implement is used as a drill, the wheel K supports its rear endat the desired height, and the axle of this Wheel carries a rag-wheel orpulley, M,

carrying a chain or belt, N, as the case may be, and

the chain orbelt also passes around a similar wheel or pulley, O, uponthe auger feed-shaft P, in the lower part of the seed-hopper G.

The contact of the seed against the pulley O, and the escape of the seedthrough the apertures traversed bythe belt, are prevented by acovering-box, Q, whose edges are made to fit the bottom and sides of thehopper.

The amount of seed sown is regplated by semi-cylindrical plates, R,which cover the feed-screw P above the apertures g, through which theseed escapes from thc hopper.

The said plates li are secured to the hopper by up# ward extensions, S,which have slots, s, through which `pass a-ttachmenffscrews, T, and thesaid screws being loosened, the plates may he adjusted, to allow thepassage of more or less grain, as stated.

The amount of seed sown maybe also regulated by 4the speed'of therotation of the feed-shaft. Y

When used as a grain-drill, the implement is as seen in iig. l, andwill, bythe use rof a single horse, drill in three rows of grain at eachtln-ough.7

XVhcn used to cover corn, the forward standard, I, is removed, (itsbrace-rod being easily disengaged from f the clevis-bolt, as beforestated,) and the belt or chain being thrown cii the pulley M, thegroulnl-wheel K, with its 4axle, is removed, and the concave-facedroller L sullstituted therefor. In this form, it will be understood thatthe horse walks in the furrow into .which the corn has :been dropped,and thc plows throw the earth therein, which is then pressed downuponthe seed by the roller L, which leaves it nicely rounded up, andsnugly tucked in to the corn.

The implement may be used as a cultivator, when in the drill-form, bymerely throwing cti the belt N.

I claim herein as new, and of my invention- The arrangement andcombination of the feed-shaft P, the pulley O., and cover Q, the belt,cord, or chain N, the pulley M, the secd-conductors H H I, the braces JJ', the plate R, furnished with the extensions S, when constructed andarranged substantially as and for the purposes set forth.

' Iny testimony oi" which invention, I hereunto set my hand.
